Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of marine equipment, in particular to a connecting structure of marine equipment and a ship body. BACKGROUND

[0002] When some large marine equipment is installed on the ship body, the bottom of the equipment is installed on the base of the ship body below the deck, and the top of the equipment needs to penetrate through multiple decks, so a through hole is formed on the deck for the equipment to pass through. In order to ensure the water tightness, the connecting structure between the top of the equipment and the deck needs to be reliable and sealed.

[0003] A Chinese utility model patent with the publication number CN205315855U discloses a through-hull structure of a ship pipeline, which has an opening (through hole) on the deck of the ship body, and the pipeline penetrates through the deck through the opening. An outer sleeve and an inner sleeve are arranged between the outer periphery of the pipeline and the inner wall of the opening, and the outer sleeve and the inner sleeve form a connecting sleeve. The inner side of the connecting sleeve is welded with the pipeline, and the outer side is welded with the deck. This through-hull connecting structure only uses welding connection, and the connection strength is low, which is suitable for light pipelines, but not suitable for some heavy large marine equipment.

[0004] A connecting structure of marine equipment and a ship body is provided. Figure 1 As shown in the figure, the ship body includes a deck 1, and the deck 1 is provided with a through hole. The marine equipment includes a top column 3 at the top, and the top column 3 of the marine equipment penetrates out of the through hole upward. The top column 3 is a hollow column, and a connecting sleeve 2 is connected between the top column 3 and the deck 1. The connecting sleeve 2 is sleeved on the top column 3 and includes a vertical connecting cylinder 22, a horizontal connecting ring 21, and a round corner transition part at the joint of the vertical connecting cylinder 22 and the horizontal connecting ring 21. The round corner transition part forms a force transmission part. The outer diameter of the horizontal connecting ring 21 is larger than that of the vertical connecting cylinder 22. The lower end of the vertical connecting cylinder 22 is connected to the hole of the horizontal connecting ring 21. The vertical connecting cylinder 22 is sleeved on the top column 3, and the horizontal connecting ring 21 is supported on the deck 1. The horizontal connecting ring 21 is welded with the deck 1 to form two welds, i.e., an inner weld 7 and an outer weld 8. The vertical connecting cylinder 22 is provided with a connecting hole, and the top column 3 is provided with a fixing hole. The connecting hole and the fixing hole correspond to each other to fix and connect the vertical connecting cylinder 22 and the top column 3 by a fastening bolt 5. The upper end of the vertical connecting cylinder 22 is welded with the top column 3 to ensure water tightness. The equipment connecting weld 6 formed by welding the vertical connecting cylinder 22 and the top column 3 forms a welded sealing structure.

[0005] The combination of bolt connection and welding can reinforce the connection structure, support the marine equipment by the connecting sleeve with certain rigidity, and is suitable for installation of large marine equipment, but the ship body will generate hogging, sagging and torsional deformation under the action of gravity, water pressure and wave additional load, the deformation of the ship body and the marine equipment is not coordinated due to the difference in local structural rigidity at the through hole, the welded sealing structure between the connecting sleeve and the marine equipment is easily damaged when the ship body generates reciprocating bending deformation, thereby leading to sealing failure and unreliable use.

[0035] Embodiment 1 of the connection structure of the marine equipment and the ship body of the present application:

[0037] The connecting sleeve 2 is an integral structure, the horizontal connecting ring body 21, the vertical force transmission cylinder body 24, the horizontal force transmission ring body 23, and the vertical connecting cylinder body 22 are integrally formed and coaxially arranged, and the thicknesses of the horizontal connecting ring body 21, the vertical force transmission cylinder body 24, the horizontal force transmission ring body 23, and the vertical connecting cylinder body 22 are consistent to facilitate molding.

[0038] The horizontal connecting ring body 21 is a plate structure, the inner diameter of the horizontal connecting ring body 21 is larger than the hole diameter of the through hole 12, the horizontal connecting ring body 21 is attached to the upper surface of the hull deck 1, the horizontal connecting ring body 21 includes a connecting ring inner edge close to the center of the horizontal connecting ring body 21 and a connecting ring outer edge away from the center of the horizontal connecting ring body 21, the connecting ring inner edge and the connecting ring outer edge are both welded with the hull deck 1 to form a deck connecting inner weld 7 and a deck connecting outer weld 8 respectively, the deck connecting inner weld 7 is at the intersection of the inner circumferential surface of the horizontal connecting ring body 21 and the upper surface of the hull deck 1, the deck connecting outer weld 8 is at the intersection of the outer circumferential surface of the horizontal connecting ring body 21 and the upper surface of the hull deck 1, by welding the horizontal connecting ring body 21 and the hull deck 1 together, a fixed connection is formed while ensuring water tightness.

[0039] The vertical force transmission cylinder 24 extends in the up-down direction, the inner diameter of the vertical force transmission cylinder 24 is larger than the hole diameter of the through hole 12, the lower end of the vertical force transmission cylinder 24 is connected with the connecting ring outer edge of the horizontal connecting ring body 21. A third round corner 27 is arranged at the joint of the lower end of the vertical force transmission cylinder 24 and the connecting ring outer edge of the horizontal connecting ring body 21 to optimize the stress at this position. The horizontal connecting ring body 21 is arranged in the space between the vertical force transmission cylinder 24 and the top column 3, avoiding occupying additional space and being conducive to increasing the distance between the vertical force transmission cylinder 24 and the top column 3 to arrange the horizontal force transmission ring body 23.

[0040] The horizontal force transmission ring body 23 is a plate structure, the horizontal force transmission ring body 23 includes a force transmission ring inner edge close to the center of the horizontal force transmission ring body 23 and a force transmission ring outer edge away from the center of the horizontal force transmission ring body 23, the upper end of the vertical force transmission cylinder 24 is connected with the force transmission ring outer edge, a first round corner 25 is arranged at the joint of the vertical force transmission cylinder 24 and the horizontal force transmission ring body 23 to optimize the stress and ensure the deformation ability of the vertical force transmission cylinder 24 and the horizontal force transmission ring body 23. The upper end surface of the horizontal force transmission ring body 23 is flush with the upper end surface of the top column 3. The horizontal force transmission ring body 23 is arranged at a relatively large distance from the hull deck 1 to arrange the vertical force transmission cylinder 24, so that the vertical force transmission cylinder 24 has a relatively large axial length, which is conducive to improving the deformation ability. The vertical force transmission cylinder and the horizontal force transmission ring body form a "convex" hollow force transmission part structure, so that the force transmission part formed by the vertical force transmission cylinder and the horizontal force transmission ring body has a certain transverse span and longitudinal extension space.

[0041] The vertical connecting cylinder 22 extends along the up-down direction, and is arranged between the inner and outer vertical force transmission cylinder 24. The inner edge of the horizontal force transmission ring body 23 is connected to the upper end of the vertical connecting cylinder 22. The junction of the vertical connecting cylinder 22 and the horizontal force transmission ring body 23 is provided with a second round corner 26 to optimize the stress at the junction. The vertical connecting cylinder 22 is sleeved on the top column 3, and the inner circumferential surface of the vertical connecting cylinder 22 is attached to the outer circumferential surface of the top column 3 to form a junction 9.

[0042] The cover ring 4 is sealed at the junction gap between the upper end of the vertical connecting cylinder 22 and the top column 3. The cover ring 4 is supported on the horizontal force transmission ring body 23 and the top column 3. The lower end surface of the cover ring 4 is attached to the upper end surface of the horizontal force transmission ring body 23 and the upper end surface of the top column 3. The cover ring 4 includes an inner edge near the center of the cover ring 4 and an outer edge away from the center of the cover ring 4. The inner edge is welded to the top column 3 to form a first weld 10. The outer edge is welded to the horizontal force transmission ring body 23 to form a second weld 11. The cover ring 4, the first weld 10 and the second weld 11 form the welded sealing structure. The first weld 10 is at the intersection of the inner circumferential surface of the cover ring 4 and the upper end surface of the top column 3. The second weld 11 is at the intersection of the outer circumferential surface of the cover ring 4 and the upper end surface of the horizontal force transmission ring body 23 to seal the junction 9. By providing the cover ring 4, the junction gap between the upper end of the vertical connecting cylinder 22 and the top column 3 is sealed, and the cover ring 4 spans the horizontal force transmission ring body 23 and the top column 3. The inner edge and the outer edge of the cover ring are welded to the top column 3 and the horizontal force transmission ring body 23 respectively to form two welds, which improves the structural strength and helps to reduce the stress between the vertical connecting cylinder 22 and the top column 3.

[0043] The vertical connecting cylinder 22 is fixed to the top column 3 by a fastener, which is a fastening bolt 5. The top column 3 is a hollow column, and the top column 3 and the vertical connecting cylinder 22 are respectively provided with bolt through holes. The fastening bolt 5 is inserted into the bolt through hole. The end of the fastening bolt 5 inserted into the top column 3 is connected to a nut. The top column 3 and the vertical connecting cylinder 22 are fixedly connected by the fastening bolt 5 to improve the connection strength of the vertical connecting cylinder 22 and the top column 3. The fastener connection structure can bear most of the force, which helps to reduce the stress at the welded sealing structure.

[0044] When the ship hull is sailing on the sea and generates hogging or sagging deformation, the bending deformation of the ship hull is transmitted to the ship deck 1, which presents as tensile or compressive deformation. Since the ship deck 1 is fixedly connected with the horizontal connecting ring body 21 through the deck connecting inner weld 7 and the deck connecting outer weld 8, the tensile or compressive deformation of the ship deck 1 is transmitted to the vertical force transmission cylinder 24, which is connected with the top horizontal force transmission ring body 23 through the first fillet 25, and thus the bending deformation of the vertical force transmission cylinder 24 is transmitted to the first fillet 25 and the horizontal force transmission ring body 23. In this way, the deformation of the ship deck 1 needs to be transmitted to the first weld 10 and the second weld 11 on the inner and outer sides of the cover ring 4 in the upper part through the horizontal connecting ring body 21, the vertical force transmission cylinder 24, the first fillet 25 and the horizontal force transmission ring body 23 of the connecting sleeve 2 in turn. The transmission path and the deformable space are greatly lengthened compared with the prior art structure. The tensile and compressive forces transmitted from the ship deck 1 are offset by the deformation of the vertical force transmission cylinder 24, the first fillet 25 and the horizontal force transmission ring body 23, which greatly reduces the stress of the welds at the cover ring 4 and ensures the water tightness and reliability of the connecting part. The connecting structure of the marine equipment and the ship hull can not only ensure the water tightness but also avoid the transmission of the deformation of the ship hull to the marine equipment, and can effectively improve the water tightness, reliability and safety of the connecting part.

In this embodiment, the upper end of the vertical connecting cylinder is directly welded with the top column body, and the vertical connecting cylinder and the top column body are welded to form a weld, which constitutes the welding sealing structure.

In this embodiment, the upper end surface of the horizontal force transmission ring body is lower than the upper end surface of the top column body, and the inner circumferential surface of the cover ring is a stepped surface to adapt to the annular stepped surface formed by the upper end surface of the horizontal force transmission ring body and the outer circumferential surface of the top column body, so that the cover ring covers the joint gap between the vertical connecting cylinder and the top column body.
